- The objectaof this invention is the provision of a machine for cleaning watch works and thelike, which is characterized by simplicity in construction and reliability Aand 4 I etlici'ency in practical use.

The invention will be fully and comprehensivel understood from a consideration of the ollowing detailed description when read in connection with the accompan ng 10 drawings which form part of the app ication, with the understanding, however, that the improvement is capable of extended application and is not confined tothe exact showing of the drawings nor to theprecise 1li-construction described and, therefore, such changes and modifications may be made therefrom as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims'.

'Fi re 11 is a sectional view approximate y on the line 11-11 of Figure 1.

As disclosed b the drawings the machine includes a base p ate 1 that is provided with compressible feet 2. The base is centrally porvided'with an opening surrounded by a 3 and in this opening there is securely vthe casing for,- this motor is indica fixed the tubular standard 4 of the machine. The standard .4 extends a suitable distance vabove the base and has its top end closed by a screw cap 5.

Resting on the upper face of the boss 3 55 there is another boss formed on the under face of a plate 6. The plate 6, in its upper face, is provided with three e idistantly spaced annular depressions 7, eali affording 'a rest for a receptacle 8. The receptacles 8 60 are of crockery, glass or like material and as the same are of cup-shaped formation they will hereinafter be referred to as cups. The supporting plate 6 for the cups is centrally formed with a tubular projection 9 that sur'65 rounds the opening through which-the standard passes,.and received in this tubularfex 'tension and. referably fixed thereto there isa sleeve 10 o a greater length than the height v f the cups 8. The sleevelO is held from lon- 70 i A'gitudinal movement on the standard, and also in contact with the bearing boss 8 by a collar 11 arranged around the standard and held in Acontact with the upper end of the sleeve by a binding ,element 12. Through the hollow .75 sleeve-there is passed thel cord 13, that encloses conductor wires, one end of the'cord being plugged to a wall socket orthe like and the other end of the cord having its wires connected to a motor of the ordinary ty e, and 30 ted) in the drawin bythe numeral 14. The motor is sustalned in a vertical position as disclosed by the drawings and has its bottom portionv provided with -an elongated neck extension 15 85 to afford a firm bearing for the motor shaft 16. 'On the top of the casing there is a knob 17 in the nature of a turnable switch for controlling or shutting oif the current to the motor. Y '.90 The 'mount or support furthe motor is of a articular and peculiar construction and orms an important feature of ,this invention. The mountis in the nature of a gimbal, the same including a fiat ring 18 that loosely re ceives the motor casindg therethrough, the said casin being provide with diametrically o posec angle brackets 19 that are suitab y.

vspaced from the ring 1 8 and that have preferloo ably loosely passed therethrough boltsn20 en.

gaged by nuts, and the bolts 20 pass through' the bores of rubber or like com ressible discs 22 while similar discs 23 are orced against the under face of the ring 18 by the nuts 24 that are screwed on the bolts 20.

The second element of the support is arranged below the ring and is in' the nature of a forked plate 25. The plate 25 is out of contact with the metal casing and the ends thereof are provided with openings that register with similar openings in the ring 18, and through these openings there are passed bolts 26 engaged by nuts 27. The bolts ass through rubber or like compressible was ers 28 that are disposed between the arms of the element 25 and the sides of the ring 18 and which discs are arranged at right angles with 4respect/tothe compressible discs 22 and 23.

Other elastic or rubber discs 29 are supported bythe bolts 26 on the upper face of the rlng l 18, being held in place by the nuts 27.

The connecting end for the arms of the forked 'support 25 is concaved and anged, as

at 30, and is bolted or otherwise secured to a its under face with three spaced circumferslide 31 on the standard 4. The standard 4 is formed with a longitudinal groove 32 and in the bore of the slide 31 there is a key 33 that is received in the said groove. There is passed through a threaded opening in the slide 31 a headed binding bolt 35 which contacts with the standard and holds the motor 14 at desired elevations with respect to the said support. -The outer end of the motor shaft 16 is threaded and has screwed thereon an open element which I will term a spider and which is indicated by the numeral 36. The lower portion of the spider is in the nature of a ring 37 formed with exterior threads and these threads are designed to be screwed in a metal ring member 38 that forms the' top element of the open frame 39 for a reticulated basket 40. Resting on the top of the element which I have termedthe spider 36 and loosely arranged on the shaft 37 there is a disc 41 that has on its outer face a boss 0r tubular enlargement 42 to steady the'same on the said shaft. In each of the cups 8 there are right-angularly arranged spaced'baflie or agitator plates 43. The plates are vertically arranged and lie a proximately in planes passing the center o the cups 8, andV resting on the plates 43 there is a disc 44 whose centralv opening 45 is arranged in a line with the inner edges of the said plates-43. A

The cup supporting plate 6 is provided on entially arranged depressions or sockets 46, each being surrounded by a depending boss 47 that rests on the base 1.

The under face of the base is provided with spaced bearings 48 for a shaft 49. The bearings` 48 are preferably formed on the ends of a plate 50 whichis riveted on the under face of the base, and the shaft 49 has its inner .end formed with an offset finger 51 provided with a teat or lug 52 that passes through an l .or outer'end of the shaft has fiXedly secured thereon a handle 53 and there is fixed on the shaft, adjacent one of the bearings 48, one end of a coil spring 54, the second end of the said spring being brought into contact with the late 50, whereby the element 52 on the sha t is at all times .influenced through its opening and into the socket 46. By this arrangement it will be noted that one of the cups 8 is at all times sustained in a position to receive the basket 40 thereinand through the central opening in the discs 44.

All of the cups 8 have deposited therein watchwork cleansing agents. The cleansing fluid in one of the cups consists of water, soap and ammonia, that in -another cup being of some non-explosive cleaning solvent similar to gasoline and that in the vremaining cup being of carbon tetra-chloride. The slide is permitted to move downwardly to arrange the basket and the watchworks contained thereinin the first cup. The disc 4l on the motor shaft 16 will contact with the disc 44 in the cup or jar 8 and will thus cover the opening 45 in the said disc 44. The motor rapidly revolves the basket. for say two minutes in the cleansing fluid. The slide is then operated to raise the basket out of the cup vor jar and the motor is again rapidly revolved when the basket is in the `air to spin the said basket and this centrifugal motion will dry the basket and .the watchworks therein. The latching means is operated while the basket is elevated to bring the next cup or jar into a position to receive the basket and watchwork in such cup and the 'operation above described is repeated. The watchworks are subject to the 'same treatment in all of the cups or jars and likewise to the rapid centrifugal action when raised outof the jars to thoroughly dry and effectively clean the watch. When the basket is lowered into the cups or jars and the disc 41 rests on or covers the openings in the discs 44 the rapid rotation of the basket by the motor will, of course,

ing for the motor permits of the shaft 16 bef .Y

ing revolved at a greater rate of speed than is ordinary and allows the basket to turn be-v 'I tween 7 ,500l and 10,000 vrevolutions per mmuteso that the cleansing solution is rapidly and effectively thrown off of the watch v andout of the basket when the basket rotates in the air andlikewise .the watch is rapidly rotated when in its cleansing bath. This high speed is madel possible only bythe gimbal support. As long as everything is in balance the elastic mounting isl not necessary but as soon as the watch is put in the basket throwing the basket out of balans@ vibration would prevent high speed. With the mounting, however, the basket is permitted to revolve upon its center of gyration instead of its geometric conter. As above stated, the lower neck or bushing for the motor casing l@ is longer and heavier than those usually employed and this. prevents whipping of the shaft from its high speed when the basket is out of balance.

Having described the invention, I claim :f-

l5 l. In a watch cleaning machine, a cup adapted to contain a cleaning fluid, baiie plates in the cup, a disc resting on the baille plates and having an opening therethrough, a high speed motor having its case mounted '20 for vertical movement above the cup, a reticulated basket affording a receptacle for the watchworks on the shaft of the motor, and a disc loosely mounted on the motor shaft above said basket to rest upon the'disc in the cup when the basket is lowered into the cup throuvh said opening.

2. watchworks cleaning machine, including a cup for a cleaning fluid having vertically disposed spaced baffle plates rising 3@ from the bottom thereof Iand terminating away from the open t-op thereof, a disc res-ting on the baffle plates, said disc having an opening therein to receive the basket, a high speed motor having its case supported for vertical movement above the cup, a reticu' lated basket for thewatchworks on the shaft of the motor, a disc loose on the motor shaft above the basket and designed to rest on the disc in the cup when the basket is positioned between the baie plates in the cup, and a mount for the motor.

3. A watchworks cleaning machine, including a cup for a cleaning fluid having vertically disposedA spaced ba-flle plates rising from the bottom thereof and terminating away from the open top thereof, a disc resting on the bafile plates, said disc having an openin therein to receive the basket therethroug a high speed motor having its case supported for vertical movement above the cup, a reticulated basket for the watchworks on the shaft of the motor, a disc loose on the motor shaft above the basket and designed to rest on the disc in the cup when thebasket is positioned betweenthe baiie plates in the cup, and means for holding the motor in vertical adjusted positions. y

In testimony whereof I affix my signature.
